We have developed a fiber consisting of a bio-based plastic, such as polyactide, modified with a reactive solid component. The invented fiber is added to cementitious systems (concrete, mortar, glue) directly in the mixing process. The integrated reactive solid components are released in the crack and form reaction products that close the crack. Furthermore, an improvement of the fire protection as well as the frost resistance of the building material by the developed fiber is conceivable.

There are several energy storage concepts, such as batteries and thermal storage. However, due to relatively high investment costs, lack of environmental compatibility, high maintenance requirements, high temperature and pressure levels, high self-discharge or lack of scalability, they do not have the potential to (cost-)efficiently cushion the strong fluctuations expected in the German and international power grid in the future.

Antibodies with two different binding functions are key drug candidates in immuno-oncology. The asymmetric architecture of such bi-specific antibodies, in which each arm can bind to a specific target molecule, makes their production enormously difficult. Also, finding two-in-one antibodies currently requires a great deal of time and technical effort.
